Apparatus and method for obtaining T2 distribution
Abstract:
A method for determining earth formation properties including a data acquisition tool and a data acquisition processor coupled with NMR sensors and a first memory; transmitting earth formation fluid data to a data processing unit comprising a processor and a second memory. Obtaining a fully polarized state echo train (EFR) and a partially polarized state echo train burst (EPR); inverting the EPR to obtain an apparent transverse relaxation time (T2app) distribution; truncating the T2app distribution by discarding the partially polarized state echo train data; completing a forward model of the EPR to obtain an additional echo train burst (EFR_B), performing a second inversion of the data set; and determining earth formation fluid properties.
